Is it safe to use nitrogen in the calcium carbide process PVC production system?
Thread Content
Have the experts considered the possibility of using nitrogen to purge the silos or storage tanks in the PVC production process via the calcium carbide method? Could there be any other risks? In the event of a fire, could calcium carbide react with nitrogen to produce calcium nitride, thereby affecting the safety of the system? This is a revolutionary hypothesis
The possibility of nitrogen and calcium carbide producing calcium nitride is virtually zero, as the reaction requires continuous high temperatures and a sufficiently long reaction time.
I think the same way; the industry uses nitrogen for purging and to protect silos, and those with more experience should have thought of this risk
There is no danger, but strict control over nitrogen purity and nitrogen moisture content is required
